I used Jonathan at ATV for my AEV 2.5" lift and AEV snorkel install earlier this year.
Very pleased with the outcome, he knows his stuff and happy to share his knowledge and they specialise in Jeeps (he has a JK - check out facebook) so you're not getting a general mechanic. Reasonable prices too.
Bit of a drive for me (Upper North) but for any major mod they would be the first point of call for me.
Only problem is you'll go there and see another jeep with lots of cool mods and you'll instantly double your mod list..
Cheers
Liam
